I would head over to a Allergy / Immunology facility such as the Park Nicollet system has in St. Louis Park. They have several Doctors that specialize in pediatric needs. What makes it tricky is Asthma can be spurred by emotional, temperature, etc. So that makes sense some at this point you don't see it now all the time. A breath lung capacity test (I think it is a peak flow meter) is what can help figure out Asthma along with the medical history. Asthma has been increasing not decreasing as a health issue. Maybe she will "grow" at of it as her lung capacity increases but depending on the severity of the asthma would effect that.

Is the source of the following two quotes:
"Sometimes an infection can be a trigger and set off an asthma flare-up. If a kid comes down with a cold or the flu, his or her airways may become more sensitive than usual. In some kids, cold air itself can cause an asthma flare-up"Not every kid's asthma is the same, so there are different medicines for treating it. It's not like curing a sore throat or an earache, when everybody gets the same medicine. Instead, the doctor will think about what causes the asthma flare-ups, how fast the flare-ups happen, and how serious they are. Then he or she will decide on the best kind of treatment."
"Some kids need to take asthma medication only once in a while, when they have a flare-up. This is called rescue medicine because it works fast to open the airways, so the person can breathe. Other kids may need to take controller medicine every day. Controller medicine works to keep flare-ups from happening."

It is nothing to be "ashamed" of. Who should be be ashamed of? Those that pick-out "higher" risk individuals and make their life harder due a condition if properly and successfully best can be, treated. Husband has Allergies
and a cousin who has Asthma from a young age. He was diagnosed with a slight asthma condition but has not needed to take that medication as does not wheeze, so it only is a bother to him a little bit! Everyone is different to the level and severity and triggers. He can deny having Asthma since he does not need to take the medications for it as it does not bother him in everyday living. Wheezing can be a medical emergency so prevention maybe the answer. He does reduce the things that make his allergies WORSE. Like Cats, many types of Dogs (most) did not spend loads of time outdoors growing up.
